Mounting structure for dash cross beam at front part of vehicle

Abstract

The invention provides a mounting structure for a dash cross beam at a front part of a vehicle. The mounting structure can effectively disperse the load to floor channels so as to reduce the load applied on floor longitudinal beams. Besides, the engine, engine pipes, pedals, and steering shaft are not interferenced, so that the layout freedom is ensured. The mounting structure is formed in a manner that, the dash cross beam arranged between front longitudinal beams in the width direction of the vehicle is divided into three parts, i.e., two side parts and a central part; the two side parts are engaged with a front surface side of a dash, and outer ends of the two side parts lean towards the front side of the vehicle so as to be engaged with the longitudinal beams; the central part is engaged with a rear surface side of the dash; and the sections of the joints of the central parts and the central part continuously form the joints of the two side parts and the central part of the dash cross beam on the front and rear surface of the dash.

Description

technical field [0001] The present invention relates to a mounting structure of a dash cross member at a front portion of a vehicle body. Background technique [0002] In a car having an engine room at the front of the vehicle body, the engine room and the interior of the vehicle compartment are partitioned by a dash panel, and dash side panels are provided on both sides of the dash panel. The lower part of the dash panel is joined to the floor that defines the floor of the vehicle compartment, and at the center of the lower part of the dash panel, at the center of the floor in the vehicle width direction, a floor tunnel (bulge) protruding upward is provided along the front-rear direction of the vehicle body. Usually, front side members are provided on both sides of the engine room, and floor side members continuous with the front side members are arranged on the lower surface side of the floor. Furthermore, in order to assist in reinforcing the dash portion, a dash cross m...

AI Technical Summary

Problems solved by technology

If the dash panel has a evasive shape to match the layout of the pedals, the shape of the dash panel may become complicated and the rigidity may decrease

In addition, in the case of the presence of the dash panel beam, the front and rear expansion parts of the dash panel cross beam need to avoid the surrounding layout, so the shape of the dash panel becomes more complicated

As a result, the local concave-convex shape will increase the drawing depth of punching, and the workability will deteriorate.
